Here we present the essence of technologies that Canon has accumulated as a camera manufacturer, covering basic knowledge on EF lenses and production technologies.
Do you know how Canon EF lenses are made?
The lens is the eye of a camera. Here is an introduction to Canon’s precision-crafted lenses, which was only made possible through the latest technology.
Find out the technology behind the camera lens, including how each lens is responsible for such roles as adjusting colors, distortion and focus, as well as changing the focal distance.link
Introduction of Blue Spectrum Refractive Optics (BR) lens, a new technology that corrects for chromatic aberrations at an exceptionally high level to make possible superior imaging performance.link
Nano USM is a new actuator developed by Canon that combines high-speed and high precision AF for still photo shooting and smooth and quiet AF for movies.link
For over 70 years, Canon has been pursuing the ideal lens. This video introduces how an image is created when light passes through a lens and also highlights Canon's technological breakthroughs in aspherical lenses, fluorite lenses and DO lenses, as well as the traditional craftsmanship that makes these lenses possible.link
EF lenses surpassed the 100-million-unit mark in April 2014, which is Canon’s first-in-the-world* achievement. This video explains in detail some of the cutting edge technologies that Canon developed over the years, including new optics, actuators and coatings.*Based upon Canon's research, as of April 22, 2014link
Canon is now the only manufacturer to incorporate fluorite in its auto-focus lenses for SLR cameras.link
The last challenge in lens design is the pair of phenomena known as ghosting and flare. Using a completely-new coating technology, SWC, Canon succeeded in overcoming those phenomena.link
DO (diffractive optics) lens elements enable telephoto lenses to be lighter and more compact while maintaining a high level of performance.link
